Welcome to Sound Deadening
Hi there! My name is Eduardo, I'm a car enthusiast from Portugal who loves silence. In this website you can check my sound deadening projects with pictures, videos, how-tos and some product reviews. Enjoy!
Current project: Opel Ampera
Deadening on the roof
Blocking wind noise and heat. The Ampera is now as silent at 120km/h as a stock Ampera at 80km/h. A great result, now under 60dB at 120km/h.
|Idle||80 km/h||120 km/h|
|Factory||29 dB||59 dB||63 dB|
|Current||28.5 dB||56 dB||59 dB|
